WILLARD ALVIN FULTON, F SPARTA, WISCONSIN.

SEPARATOR.

To all whom it may concern Be it known that I, WILLARD A. FULTON,

- a citizen of the United States, residing at Sparta, in the county ofMonroe and State of Wisconsin, have invented certain new and usefulImprovements in Separators, of which the following is a specification.

My invention relates to improvements in separators, and has for itsleading object the provision of an improved machine of the centrifugaltype which will readily and satisfactorily serve to separate the milkand cream from a mixture of full milk.

A further object of my invention is the provision of a machine of thischaracter which shall be of simple construction and shall have its partsso secured together as to be readily separable to permit of thoroughcleaning or replacing of the said parts.

Other objects and advantages of my improved separator will be readilyapparent by reference to the following description taken in connectionwith the accompanying drawings, and it will be understood that I maymake any modifications in the specific structure shown and describedWithin the scope of my claims without departing from or exceeding thespirit of the invention.

Figure 1 represents a side elevation of my complete separating bowl orreceptacle. Fig. 2 represents a vertical sectional view thereof. Fig. 3represents a cross sectional view of the same. Fig. 4 represents adetailed view of the'basal or supporting section. Fig. 5 represents aview of the sleeve member mounted upon said base section. Fig. 6represents a top plan view of one of the separating disks. Fig. 7represents a bottom plan view of the said disk. Fig. 8 represents adetailed view of the cream guiding cover. Fig. 9 represents a top planview of my separator. Fig. 10 represents a perspective view of the bowlnut or sleeve of the separator.

In the drawings, the numeral 1 designates the cylindrical shaft of thebasal member of my separator, said cylindrical member having a threadedupper end 2 and having a flaring base 3 formed with the upturned flange4L. Formed in three sides of the cylindrical portion 1 are grooves 5 incommunication with the central passage 6 formed through the threadedportion 2. To rotatably support said member 1, I form in Specificationof Letters Patent.

it the central conoid shaped recess 7 in Fitting over the member 1 isthe sleeve member 9 held spaced from the member 1 by the ribs 10 of themember 1, said sleeve having a flaring basal portion 11 terminating in adepending flange 12 resting 011 the base portion 3, the flange 12 thusholding the flaring portion 11 spaced above the portion 3 of the basesection. At its upper end the sleeve 9 has a reduced neck 13 adapted tofit above grooves 5. The sleeve 9 is formed with the longitudinallyextending guide ribs 14: while mounted upon said sleeve are the conoidseparating disks 15 having recesses 16 formed therein to receive theribs 14, said recesses and the central aperture 17 of the disks beinglarger, however, than the sleeve and ribs thereof whereby a slight spaceis provided between the outer face of the sleeve and the inner edge ofthe disks. The disks are formed with upwardly curving outer edges 18,and alternate disks are provided with a plurality of lugs or projections19 extending from each side thereof, said projections serving to engagethe adjacent disks and thus to hold the various disks slightly spacedfrom each other.

Fitting over the uppermost of the disks 15 is the cover section 20 heldspaced from the uppermost disks by the lugs 19, said cover sectionfitting loosely around the neck 13 of the sleeve and having a reducedportion 21 extending upward along said neck, while formed on the outerface of the cover 20 are the ribs 22.

Fitting over the complete structure pre viously described is theinclosing casing for my separator comprising a flaring portion wardaround but is spaced from the periphery of the disks 15, said tubularportion 24: having its lower edge fitting inside of the upstandingflange 4: of the member 1, a rubber ring or gasket 25 being insertedbetween the flange 4 and the member 24: to insure a fluid tight jointbetween the casing and flange of the base.

The flaring portion 23 has a reduced neck 26 adapted to fit tightlyagainst the neck 21 of the cover while formed at the base of the neck 26is an aperture or passage 27 attording communication with the space 28inclosed between the cover 20 and flaring portion 23, said passageaii'ording an outlet for the skimmed or separated milk. To re tain thevarious parts in position, I screw upon the threaded portion 2 of thebasal member 1 the internally threaded collar 29 hearing at its lowerend against the top of. the neck 26, while formed in the necks 21 and 26just below said collar are the alined apertures 31 affording an outletfor the separated cream and fitted therein is a screw which regulatesthe density of the cream and through which the cream passes. In the useof my separator, I pour the full milk into the passage 6 of member 1,the milk passing downward through the passage 6 and thence into thegrooves 5 to till the space between the member 1 and the sleeve 9.Formed in the flaring portion is an aperture 32 the milk passing throughsaid aperture from the space included between the base portion 3 and theflaring portion 11 of the sleeve. To allow the whole milk to pass upwardthrough the various disks I form in said disks the apertures 33,partially surrounded by the lips 83. In the use of my separator, as thesame whirls on the spindle as a pivot, the heavier milk will moveoutward, while the cream will tend to cling to the sleeve 9 and willpass upward along said sleeve, the skimmed milk passing upward betweenthe outer edges of the disks and the portion 24 of the casing. The creamwill consequently pass upward inside the cover section 20 and neck 21 ofsaid cover section and will be discharged through the apertures 31,while the milk will pass upward in the space 28 and out from said spacethrough the discharge aperture 27 passing out over shoulder 30 on casing23. This shoulder is import-ant as otherwise the milk would follow downsides of casing 28 in stead of throwing clear into receiving cover.

From the foregoing description taken in connection with the drawings,the construction and operation of my improved separator will beunderstood and it will be seen that I have provided a thoroughlyetficient separator of simple construction which may be readily cleansedor disassembled and which will consequently be extremely desirable froma sanitary standpoint as well as on account of its efliciency.

I claim:

l. A separator, comprising a support, a base member rotatably mounted.on the support and having a threaded upper end, said member having acentral passage formed through said threaded upper end and havinglongitudinally extending grooves formed therein in communication withthe passage, an inclosing sleeve loosely mounted on the base member andclosing the upper ends of said grooves, separating disks mounted on thesleeve, an inclosing casing for the device, and a sleeve secured on thethreaded end of the base member.

2. In a separator, the combination with a basal member having a threadedupper end and having a passage formed through said upper end andterminating in grooves formed in the base member, of an inclosing sleeveand a casing having reduced necks fitting around the base member, saidinclosing sleeve inclosing the upper ends of the grooves and a sleeveformed with internal threads for engagement on the threaded portion ofthe basal member, said sleeve bears against the necks of the inclosingsleeve and casing to secure said parts in position.

8. A separator, including a base section, a sleeve surrounding the baseand spaced therefrom, means for introducing full milk into said space,separator disks carried by the sleeve, said sleeve and disks havingapertures formed therein for the passage of the milk, apertures in disksbeing spanned by lips, a cover section mounted on the sleeve above thedisks, and an inclosing casing, said cover section and easing having anaperture formed at the upper portion thereof for the exit of cream andthe casing having apertures formed therein for the exit. of milk fromthe space between the cover section and easing.

In testimony whereof I 'atlix my signature, in the presence of twowitnesses.
